What if I have a static IP address?

If your IP is static, then you CAN’T change it
without contacting your ISP. Although not impossible, it is very rare
that an ISP would assign you a static IP without some sort of increased
level of service like a business account. However, an ISP can set a
lengthy lease time for your IP address and make it look like you've
assigned a static IP. If you have a long lease time (explained in this
article) on your IP then you may not be able to change your IP address
without leaving your modem or router unplugged for a long period of
time (more than 8 hours), or without cloning your MAC address, which
I’ll explain later in this article.
It definitely helps if you know how the IP is being assigned to you.
You can read our DHCP definition to get a better understanding.

What is an IP address lease time?

An IP lease time is the amount of time your ISP determines
you’ll be assigned a particular IP. Some IP lease times could be just a
couple of hours, where some are set to a few days, and other IP lease
times could be set for as long as a year or more. This setting is
completely up to your ISP.
One of the easier methods to change your IP address is to turn off your modem/router/computer overnight. Then turn it back on the following morning. This method WILL NOT work if your ISP has a long lease time set for your IP.
The following method will ONLY work if your computer is being assigned your external IP and not a router.How to determine if your computer is being assigned the external IP
If your connection is direct to your computer and your computer gets the public IP and not a router, you can try this:
For Windows 2000, XP, and 2003
1. Click Start
2. Click Run
3. Type in cmd and hit ok (this opens a Command Prompt)
4. Type ipconfig /release and hit enter
5. Click Start, Control Panel, and open Network Connections
6. Find and Right click on the active Local Area Connection and choose Properties
7. Double-click on the Internet Protocol (TCP/IP)
8. Click on Use the following IP address
9. Enter a false IP like 123.123.123.123
10. Press Tab and the Subnet Mask section will populate with default numbers
11. Hit OK twice
12. Right click the active Local Area Connection again and choose Properties
13. Double-click on the Internet Protocol (TCP/IP)
14. Choose Obtain an IP address automatically
15. Hit OK twice
16. Go to What Is My IP to see if you have a new IP address

For Vista (Windows 7 is very similar)
1. Click Start
2. Click All Programs expand the Accessories menu
3. In the Accessories menu, Right Click Command Prompt and choose Run as administrator
4. Type ipconfig /release and hit enter
5. Click Start, Control Panel, and open Network and
Sharing Center. Depending on your view, you may have to click Network
and Internet before you see the Network and Sharing Center icon
6. From the Tasks menu on the left, choose Manage Network Connections
7. Find and Right click on the active Local Area
Connection and choose Properties (If you’re hit with a UAC prompt,
choose Continue)
8. Double-click on Internet Protocol Version 4 (TCP/IPv4)
9. Click on Use the following IP address
10. Enter a false IP like 123.123.123.123
11. Press Tab and the Subnet Mask section will populate with default numbers
12. Hit OK twice
13. Right click the active Local Area Connection again and choose Properties
14. Double-click on Internet Protocol Version 4 (TCP/IPv4)
15. Choose Obtain an IP address automatically
16. Hit OK twice
17. Go to What Is My IP to see if you have a new IP address
Some people have inquired about manually
assigning their IP address. This IS possible, but you run a very high
risk of your ISP banning you from connecting to the internet. To
manually change your IP, follow the steps above for your
Operating System. In step 9 or 10, depending on your O/S, enter an IP
similar to the one displayed in the command prompt window. For example,
if the IP displayed in the command prompt window is 75.1.2.3, change
yours to 75.1.2.4. You’ll also need to manually enter the Subnet,
Gateway and DNS Server IP addresses. If the new IP you give your
computer doesn’t work, chances are someone else on the ISP network has
already been assigned that IP. You’ll need to move on to the next one
and keep trying until you find an open one. Keep in mind that some ISPs
match up your MAC or modem data to the address that’s been assigned. If
those 2 things don’t match up, you won’t be able to connect no matter
what. If your router gets the IP and not your computer, you’ll need to
http in to your routers interface and manually assign the IP there. It’s
pretty much the same method as assigning the IP to your computer. The
method that varies is in how you reach your routers interface. You can
get the instructions from your manufacturer’s website.
MAC Cloning. What is a MAC address? A MAC address
is a physical hardware address assigned to each device that has the
capability of connecting to a network. The internet is nothing more than
a large network. The MAC address is something that is assigned in the
chip on the device and is not something the user can change. MAC cloning
can only be done at your router providing it has those capabilities.
Most ISPs assign their IPs based on the MAC address in your equipment.
If the MAC address of your router is 00-11-22-33-44-55 and you connect
to your ISP, the DHCP server records your MAC and assigns an IP. If you
disconnect from the ISP, you lose your IP address. The next time you
connect, the DHCP server sees your MAC, looks to see if it has assigned
an IP address to you before. If it has and the lease time has not
expired, it will most likely give you the same IP address you had before
disconnecting and will not change your IP.

Why clone a MAC address?

Getting a new MAC address most likely equals a new IP. How to
clone your MAC and if your router has this feature is dependent on the
router itself. You’ll need to find the instructions on the
manufacturer’s website. We offer a Quick Reference List on our Router Support page.

The IP Address Lookup tool also referred to as IP Lookup,
Lookup IP, Lookup IP Address, IP Address Location, IP Location, and IP
Locator is designed to give you an idea of where your IP Address or the IP Address
you lookup is located. This tool is not 100% accurate due to many
different factors. Some of those factors include where the owner of the
IP has it registered, where the agency that controls the IP is located,
proxies, cellular IPs, etc. If you are in the US and the controlling
agency of the IP is located in Canada, chances are the IP address lookup
results will show as Canada. Showing a Canadian IP while in the US is
very common among Blackberry users on the Verizon network.
The results of this IP Address Lookup utility include
the IP Address, City, Host Name, Region / State, Postal / Zip Code,
Country Name, Country Code, Time Zone, Longitude, Latitude, ISP, Domain
Name, Net Speed, and IP Decimal.
Often, people think if they perform and IP address lookup,
that they are going to find the physical mailing address of the user
assigned the IP in question. This is simply not true. At this time, we
are not aware of any IP address database that will give you the exact
physical postal address of the IP address you lookup. At best, you'll
get the exact city in which the user of the IP is located. For an exact
physical address you would need to contact the ISP (Internet Service
Provider) of the IP address in question. However, without a police
warrant, or some sort of legal document forcing the ISP to turn over the
information, don't expect them to give you the mailing address of the
user that was assigned the IP at the time you received the offensive
email, or other means of offensive / questionable communication from
said IP. The best you can do in this case is to file a complaint with
the ISP and forward them all of the information from the questionable /
offensive communication regarding the complaint. If you have any
questions about the IP Address Lookup tool or the results, please check
out our IP Address Lookup Forum.

Our visitors need to know their IP address
for many reasons including gaming, tech support, remote desktop
connection, proxy detection, anonymity, to see if their address has
changed, or if they're running thier own email server. If you need to
run your own email server or web server, it would be best to have a static IP address. Alternatively, an IP VPN (or virtual private network) can also be utilized for added network security. Visitors often come here to do an IP Address Lookup to find the location of an IP address. Some folks might've gotten a spam email and want to learn How To Trace An Email. Others might ask themselves How Do I Change My IP. Whatever your reason for visiting, welcome.

Internet Protocol Address:

This number is an exclusive number all information
technology devices (printers, routers, modems, et al) use which
identifies and allows them the ability to communicate with each other on
a computer network. There is a standard of communication which is
called an Internet Protocol standard.
In laymans terms it is the same as your home address. In order for you
to receive snail mail at home the sending party must have your correct
mailing address (IP address) in your town (network)
or you do not receive bills, pizza coupons or your tax refund. The
same is true for all equipment on the internet. Without this specific
address, information cannot be received. IP addresses may either be
assigned permanently for an Email server/Business server or a permanent
home resident or temporarily, from a pool of available addresses (first
come first serve) from your Internet Service Provider. A permanent number may not be available in all areas and may cost extra so be sure to ask your ISP.Domain Name System (DNS): This allows the IP
address to be translated to words. It is much easier for us to remember a
word than a series of numbers. The same is true for email addresses.
For example, it is much easier for you to remember a web address
name such as whatismyip.com than it is to remember 192.168.1.1 or in the
case of email it is much easier to remember email@somedomain.com than
email@192.168.1.1Dynamic IP Address: One that is not static and
could change at any time. This type is issued to you from a pool of
addresses allocated by your ISP or DHCP Server. This is for a large
number of customers that do not require the same address all the time
for a variety of reasons. Your computer will automatically get this
number as it logs on to the network and saves you the trouble of having
to know details regarding the specific network configurations. This
number can be assigned to anyone using a dial-up connection, Wireless
and High Speed Internet connections. If you need to run your own email
server or web server, it would be best to have a static IP address.Static IP Address: One that is fixed and never
changes. This is in contrast to a dynamic IP address which may change at
any time. Most ISP's can offer to assign a single static IP or a
block of static IP's for a few extra bucks a month and may require you
upgrading to a business account.IPv4: Currently used by most network devices.
However, with more and more computers accessing the internet, IPv4 IPs
are running out quickly. Just like in a city, addresses have to be
created for new neighborhoods but, if your neighborhood gets too large,
you will have to come up with an entire new pool of addresses. IPv4 is
limited to 4,294,967,296 IPs.IPv5: This is an experimental protocol for UNIX
based systems. In keeping with standard UNIX (a computer Operating
System) release conventions, all odd-numbered versions are considered
experimental. It was never intended to be used by the general public.IPv6: The replacement for the aging IPv4. The
estimated number of unique IPs for IPv6 is
340,282,366,920,938,463,463,374,607,431,768,211,456 or 2^128.
The old and current standard of IPs was this: 192.168.100.100 the
new way can be written different ways but means the same and are all
valid:
* 1080:0000:0000:0000:0000:0034:0000:417A
* 1080:0:0:0:0:34:0:417A
* 1080::34:0:417A
